Halogen - Cov nplaim dawb - retland thiab cable khoom
TPU muaj cov khoom muag zoo heev, hnav tsis kam, siab thiab kub thiab txias thiab kub}
Nrog kev txhim kho cov neeg txuas ntxiv ntawm cov neeg muaj kev tiv thaiv ib puag ncig thiab hluav taws kub, thiab lwm yam tshiab} Cov xov xwm dawb}}} retardant xov thiab cable. Yog li ntawd, Halogen - Cov nplaim dawb- ret thru xov hlau thiab cables yog qhov xav tau zoo hauv kev ua lag luam.
Sealing nplhaib, ncoo
TPU muaj cov yam ntxwv ntawm kev txhaj tshuaj molding thiab extrusion. Nws tuaj yeem npaj cov ntaub ntawv sealing rau kev sib txawv los hloov cov roj hmab vuas luaj li cas thiab txo cov nqi ntawm cov khoom siv uas muaj ntau yam los ntawm cov khoom siv hluav taws xob ntau ntxiv tuaj yeem tsim los ntawm cov khoom siv thermal.
Nrog kev nthuav dav ntawm daim ntawv thov TPU, qhov yuav tsum tau ua rau nws tau txais txiaj ntsig siab dua thiab siab dua, tshwj xeeb tshaj yog cov kev xav tau ntawm daj tsis kam thiab kev laus tiv thaiv. Vim li no, cov khoom siv hluav taws xob tshiab tuaj yeem ua tau raws li kev nce kev lag luam ntxiv.Yog yav dhau los, polyurethane siv Isocyanates. Vim tias muaj qhov tsis tau tso cai ob daim ntawv cog lus, yellowing thiab laus yog qhov kev tsis txaus ntseeg ntawm polyurethane. Kev tsim kho tshiab aliphatic isocyanates thiab alicyclic isocyanates tuaj yeem daws cov teeb meem no. Muaj ntau cov polyurethane elastomers nyob hauv tsev thiab txawv teb chaws, uas tau ua yeeb yaj kiab rau yav tom ntej
